Well considering I'm putting around 80 to 90 lbs of lead shot in the swingarm and will carry additional ballast for traction on the salt I went with the steel subframe. I am running two swingarm's one weighted for the salt and one stock for the mile and mile and a half, I did modify the subframe and knocked off about 1 1/2 lbs.

Looking good. Are you planning on going to the Colorado mile this year?

w'ell see, went to the Texas Mile last week with my CBR1000rr last and best run 180.7. Not bad for a stock bike with a tune. As far as the bike, the bodywork is mounted, today I built the fuel cell, next start all the plumbing

Yes, a standing mile is a lot more difficult to achieve top speeds, and even more so when you're at almost 6000 feet in elevation!

At Bonneville 2011 I got a 204.5 time slip on a stock Gen II with gutted stock mufflers, MR12, PC-V, ceramic wheel bearings, lowered 2" at each end. Valve cover had never been off.
With that being said, I was running 196-197 for days and got a fluke run where I got some help. In my mind I either got a big wind push going through the traps, the timing equipment screwed up or else they mixed up the slips.
One way or another I got the slip that said I did it, legit or not!!!!!!

Yeah, OutlawBusa went 202mph on a gen2 with an Alienhead, tune and rear sprocket.
To the OP, the gen2 has about 20 more hp than the gen1. So that's enough for a little more top end. The gen2 can do a best of 197mph stock.

If I read the rules right land speed and SCTA rules are different for production, SCTA rule 7.3/ 7.3.3 Production engines shall be the same model as the frame being used and shall have STOCK EXTERNAL APPERANCE. It is written just like that. My interpretation is I can do anything inside the engine and inside the exhaust I want as long as I retain the stock bore. I may be wrong but that's how I read it.
Ok the bike has been slow going but I'm back at it. I had to raise the back of the air box because it was hitting the injector plugs and the angle was off about ten degrees causing the intake boots to have a 1/4" gap on the back where the connect to the throttle bodies. Not sure if it would cause a problem or not so I just fixed it. Got the fuel cell done, I used the stock pump housing, took off the fuel sending unit, milled out the housing to fit a Walbro pump and beefed up the wiring inside. Added a billet fuel rail with an Aeromotive bypass reg. The main harness is hooked up and working with 2 8 cell Antigravity Batteries so I can supply 24v to the starter. I also cut the bottom of Hayabusa fuel tank, I used the fuel pump seal on my tank and will use the top as a cover. I've mounted a Davies Craig EPW under the tank and the pump and fan controls will up top somewhere, and I had an old Mr Gasket cool can so I think I'll put it in the tail somewhere, I'm not sure if they work but it can't hurt. I'm waiting on some miscellaneous parts to finish up the fuel system. I'm not far off from starting the bitch!!!

Hi. Very very nice work. I like the cool can it is best to keep the fuel as cool as you can. Did you use any heat shied for your tank and fuel lines? Do you need to put fire protection on the fuel lines? In my class I have to and it helps to keep the fuel cooler too.

I have heat shield for the air box, Tank and fuel lines plus insulation for the fuel lines. Just have not installed it yet. Getting the wiring tidied up right now
I don't have a copy of the 2018 rules, but I do remember from the years past .... Overall: The intent of Production is that if you place a showroom stock bike next to a "Production" class bike, and a bike guy can't tell them apart. There is a rule that says if you stand behind the exhaust and look into the opening, you can't tell if it has been modified. They get really particular on Production. Heck, I personally know of a fellow racer that was denied a record in Production because he was running SS branded brake lines.
On engine size; you can run "up" to the class limit. A gen 1 Busa can run up to 1349.9 cc but not over.

Ok it's been a while with my daughters wedding, finishing up some customers bikes ans so on, so starting today I'm full time on the bike. I picked up some parts from Lookin4abusa's turbo bike. I did get the cooling system finished up with a Craig Davies EWP and fan controller, now it's on to the fuel system. I finished up the tank today. I had already built the bulk of the fuel cell, I took the busa tank and cut the bottom out and will use the shell as a cover, then I took the stock fuel pump and removed the fuel sending unit, regulator and stock pump. Installed a walbro H.V. pump with an external Aeromotive filter and regulator
Any more pics of the battery box here, and/or model numbers on the batteries. I'm loving that setup
